Marti Ahtisaari, a special UN envoy for talks on Kosovo, has proposed that the province be granted internationally supervised sovereignty, but Serbian authorities have strongly opposed the plan as threatening Serbia's national sovereignty and territorial integrity.
"We will be checking how existing UN Security Council resolutions on Kosovo, particularly Resolution 1244, are being implemented," Sergei Lavrov said. "We want to objectively, without imposing any one-sided evaluations, determine who was implementing UN Security Council resolutions and how, and who was not."
On Monday Ahtisaari returned his proposals on the future status of the breakaway Serbian province to the UN Security Council following fruitless top-level talks in Vienna between Pristina, Belgrade and the European Union, which said later in a statement that it fully backed Ahtisaari's plan.
As a veto-wielding member in the 15-nation UN Security Council and a traditional ally of Serbia, Russia has insisted that a decision on Kosovo should satisfy both Kosovar and Serbian authorities, and that it must be reached through negotiations.
Serbia's predominantly ethnic Albanian Kosovo province, which has a population of two million, has been a UN protectorate since NATO's 78-day bombing campaign against the former Yugoslavia ended a war between Serb forces and Albanian separatists in 1999.
The Serbian parliament unanimously approved a resolution February 14 rejecting some provisions of the plan.
Unlike Russia, NATO has made it clear that it favors independence for Kosovo, but a final decision will be up to the UN Security Council.
